Title:
ELECTROMAGNETIC BRAKE DEVICE AND OPENING/CLOSING BODY CONTROL DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2020125833
Kind Code:
A
Abstract:
To correctly control a brake force.SOLUTION: An electromagnetic brake generates a brake force corresponding to a current value I which is carried to an excitation coil irrespective of an electricity-carrying direction with respect to the excitation coil. A door ECU as a brake control part comprises a current command value calculation part for calculating a current command value Io corresponding to a brake force generated by the electromagnetic brake, and a current control part for controlling electricity-carrying to the excitation coil on the basis of the current command value Io. Then, when the current command value Io is reduced, the current control part inverts the electricity-carrying direction, and performs electricity-carrying control based on the current command value Io.SELECTED DRAWING: Figure 10
